Best way to consist between attributes validation and Postgres level

attributes do
    uuid_primary_key :id

    attribute :name, :string do
      allow_nil? false
      public? true
      constraints min_length: 3, max_length: 70, trim?: true

      description "Human-readable site name"
    end

    attribute :host, :string do
      allow_nil? false
      public? true
      constraints min_length: 3, max_length: 200, trim?: true
      description "Domain name for the site (e.g., example.com)"
    end

    attribute :priority, :integer do
      default 0
      public? true
      constraints min: 0, max: 100
      description "Priority for site routing (higher = more priority)"
    end

    attribute :active, :boolean do
      default true
      public? true
      description "Whether the site is currently active"
    end

    create_timestamp :inserted_at
    update_timestamp :updated_at
  end

   check_constraints do
      check_constraint :name, "name_length_check", 
        check: "length(name) >= 3 AND length(name) <= 70",
        message: "Name must be between 3 and 70 characters"

      check_constraint :host, "host_length_check", 
        check: "length(host) >= 3 AND length(host) <= 200", 
        message: "Host must be between 3 and 200 characters"

      check_constraint :priority, "priority_range_check",
        check: "priority >= 0 AND priority <= 100",
        message: "Priority must be between 0 and 100"

      # Multiple attributes can share the same constraint
      check_constraint [:name, :host], "no_empty_strings",
        check: "name != '' AND host != ''",
        message: "Name and host cannot be empty"
    end
